1 Claim. (Cl. 7237) This invention relates to new and useful improvements in building blocks and the primary object of the present invention is to provide a building block so constructed as to form a wall having a siding effect with each block having a tongue or lip portion that will overlap the upper portion of a block immediately below it.

Another important object of the present invention is to provide a wall structure composed of siding simulating building units or blocks with novel and improved binding means joining adjacent courses of blocks and concealed from the exterior of the wall.

A further object of the present invention is to provide building blocks of two types one of which may be employed in forming a wall and the other of which may be applied to the outer surface of a rough wall in order to form a siding or clapboard effect.

A still further aim of the present invention is to provide a building unit of the aforementioned character that is simple and practical in construction, strong and reliable in use, neat and attracive in appearance, inexpensive to manufacture, install and replace, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and the operation as more fully hereinafter described and claimed, references being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a fragmentary perspective view of a wall constructed by using one form of the present building block;

Figure 2 is a transverse vertical sectional view of Figure 1;

Figure 3 is a perspective view of one form of the present building block;

Figure 4 is a vertical sectional view of a wall structure embodying the second form of building block; and,

Figure 5 is a perspective view of the building block employed in conjunction with the wall shown in Figure 4.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral represents one type of building block composed of an elongated body of suitable material, such as cinders, cement, plastic or the like, having flat, horizontal upper and lower faces 12 and 14, a flat vertical inner face 16 and a downwardly and outwardly inclined fiat outer face 18.

The body 10 is formed with the usual vertical bores 20 for ventilating purposes. The upper forward corners of the blocks 10 are beveled to provide vertically inclined surfaces 22 at the junctures of the walls 12 and 18 for a purpose later to be more fully described.

A rib or tongue 24 is formed on the lower wall 14 of each block 10 at its forward corner and the ribs 24 are provided with flat vertically inclined outer surfaces 26 that are flush with the outer faces 18.

One end wall 28 of each block 10, except for the end blocks, is formed with a pair of spaced parallel ribs 30 and 32. The other end of each block 10, except the end blocks, are formed with a pair of spaced parallel ribs 34 and 36. The ribs 36 are formed with downwardly and outwardly inclined outer surfaces flush with the outer faces 18 of block 10 and the surfaces 26 of rib 24.

One type of end block 38 is similar to the intermediate blocks 10 but one of their corners is formed with a vertical recess 40. The other type of end block 42 is similar to the blocks 10 but is formed with a vertical tongue 44 that will enter the recess of an adjacent end block 38.

In forming a wall, such as shown in Figure 2, a first course of blocks 10 is laid and mortar M placed on their upper faces and surfaces 22. Then the second course is laid with considerable mortar binding ribs 24 to surfaces 22 and with the ribs of the second course overhanging the faces 18 of the first laid course. The mortar will be concealed and the finished wall will appear as shown in Figures 1 and 2 in the form of siding or clapboards with increased strength over such wooden siding.

The ribs 32 and 34 of adjacent blocks 10 in each course will abut each other, whereas the ribs 30 and 36 will be engaged in side by side relation as shown in Figure 1, and this later arrangement will also occur where the end blocks 38 or 42 engage a block 10.

Reference is now made to Figures 4 and 5, wherein the block 18a is solid and without core openings such as 20 in blocks 10. In this embodiment the blocks 10a are half blocks, that is the same are of a depth substantially half the depth of blocks 10 or conventional blocks.

Blocks 10a include fiat horizontal upper and lower faces 12a and 14a, flat vertical inner faces 16a and downwardly and outwardly inclined outer faces 18a. The undersurfaces of the blocks 10a are each integrally formed with a rib 24a. The ribs 24a extend throughout the length of the blocks 10a and include downwardly and outwardly sloping outer longitudinal edges 26a that are flush with faces 18a.

The blocks 10a are secured to the outer wall surface S of a building structure B in courses such as shown in Figure 4 and the lips or ribs of one course of blocks overlap the upper end portions of the course immediately below it.

The juncture of surfaces 12a and 18 are provided with c downwardly and outwardly inclined surfaces 22a to permit the mortar to secure the ribs 24a of one course to the blocks of an adjacent course, the mortar bonding the blocks 10a to the outer wall surface S.

During construction, mortar joints are employed between the ribs 30 and 32 and the adjacent end of an adjacent block, however, the end surfaces of the blocks between ribs 30 and surface 18 will abut an adjacent block without the use of a mortar joint.

Having described the invention, what is claimed as new is:

A building block comprising a body member having an inner, upright face, a downwardly and outwardly inclined outer face and upper and lower generally horizontal faces, a rib integrally formed with said body member at the line of juncture between the outer inclined face and the lower horizontal face, said rib depending below said lower horizontal face and extending substantially throughout the length of the block, said rib having an outer face substantially flush with the inclined outer face of the body,

' and having an inner surface extending downwardly from said lower horizontal face, the portion of said inner surface adjacent to the lower edge of the rib being substantially parallel to the outer inclined face of said body member, said body member at the upper outer edge thereof being beveled to provide an upper inclined surface extending downwardly and outwardly with respect to said horizontal surface, the upper horizontal surface 8 of the block between said upper inclined surface and the upright face of the block being less in dimension than the lower horizontal face of the block rearwardly of said rib, said rib depending below the lower horizontal face of the body memberra distance in excess of the vertical extent of said upper inclined surface by an amount greater than the thickness of a mortar joint so that when two such blocks are superimposed with an intervening layer of bonding mortar and with the inclined portion of the inner surface of the rib of the upper block in face contact with the outer inclined face of the lower block adjacent to the upper inclined surface thereof, a substantial portion of the inner surface of the rib opposite the upper inclined tact with the mortar of said joint.
